Effects of Mouthrinsing and Gargling to CT Values of SARS CoV-2 DATASET

<strong>Background:</strong> Coronavirus disease 2019 can spread rapidly. Surgery in the oral cavity poses a high risk of transmission of severe acute respiratory syndrome coronavirus 2. The American Dental Association and the Centers for Disease Control and Prevention recommend the use of mouthwash containing 1.5% hydrogen peroxide (H₂O₂) or 0.2% povidone iodine (PI) to reduce the viral load in the upper respiratory tract and decrease the risk of transmission. The aim of the present study was to analyze the effect of mouthrinsing and gargling with mouthwash containing 1% PI, 0.5% PI, 3% H₂O₂, or 1.5% H₂O₂ and water on the cycle threshold (CT) value. <strong>Methods:</strong> In total, 69 subjects recruited from Persahabatan General Hospital who met the inclusion criteria were randomly assigned to one of four treatment groups or the control group. The subjects were instructed to gargle with 15 mL of mouthwash for 30 s in the oral cavity followed by 30 s in the back of the throat three times per day for 5 days. CT values were collected on postprocedural days 1, 3, and 5. <strong>Results:</strong> The results of the Friedman test significantly differed among the groups. The CT values increased from baseline (day 0) to postprocedural days 1, 3, and 5. <strong>Conclusions:</strong> Mouthrinsing and Gargling with mouthwash containing 1% PI, 0.5% PI, 3% H₂O₂, or 1.5% H₂O₂ and water increased the CT value. <strong>Background:</strong> Coronavirus disease 2019 can spread rapidly.
